**The price of a book increases from $40 to $50. What is the percentage increase in the price of the book?

Solution:

The percentage increase is calculated by the formula:

Percentage Increase=New Value−Old ValueOld Value×100\text{Percentage Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100
Percentage Increase=50−4040×100=1040×100=25%\text{Percentage Increase} = \frac{50 - 40}{40} \times 100 = \frac{10}{40} \times 100 = 25\%

***A shopkeeper buys a book for $40 and sells it for $50. What is the profit percentage?

Solution:

The profit is:

Profit=Selling Price−Cost Price=50−40=10

The profit percentage is:

Profit Percentage=ProfitCost Price×100=1040×100=25%
\text{Profit Percentage} = \frac{\text{Profit}}{\text{Cost Price}} \times 100 = \frac{10}{40} \times 100 = 25\%

**The ratio of the ages of two brothers is 4:5. If the elder brother is 25 years old, how old is the younger brother?

Solution:

Let the younger brother's age be xx. According to the ratio, we can write:

x25=45\frac{x}{25} = \frac{4}{5}

Solving for xx:

x=45×25=20x = \frac{4}{5} \times 25 = 20

So, the younger brother is 20 years old.
